Abstract
Front-Dreirad 1 dadurch gekennzeichnet, dass der Rahmen einen tiefen Durchstieg mittels eines tiefliegenden Rahmenbogens 2 (1) besitzt.Front tricycle 1, characterized in that the frame has a deep passageway by means of a low lying frame bow 2 (1).
Description
Die Erfindung beschreibt ein Dreirad mit 2 Rädern im Frontbereich des Benutzers
Stand der Technik:State of the art:
Handelsübliche Front-Dreiräder herkömmlicher Bauart sind in der Regel aus einer einteiligen Rahmenkonstruktion ähnlich eines Zweiradrahmens gefertigt. Durch die Anordnung der Treteinheit unterhalb des Sattels, sitzt der Benutzer aufrecht in einer entsprechenden Höhe zum Boden. Durch die Anordnung des Lenksystems im Griffbereich des Fahrers mit ausgestreckten Armen, ist der Abstand zwischen dem Sattel und den 2 Vorderrädern relativ groß. Die Rahmengeometrie sieht in der Regel einen relativ hohen Durchstieg vor um die Steifigkeit des Rahmens zu gewährleisten.Commercially available front tricycles of conventional design are usually made of a one-piece frame structure similar to a bicycle frame. Due to the arrangement of the tread unit below the saddle, the user sits upright at a corresponding height to the ground. The arrangement of the steering system in the grip area of the driver with outstretched arms, the distance between the saddle and the two front wheels is relatively large. The frame geometry usually provides a relatively high pass to ensure the rigidity of the frame.
Problemstellung:Problem:
Die Front-Dreiräder nach dem bisherigen Stand der Technik beinhalten das Problem
- 1: Für das Aufsitzen auf den Sattel, muss ein Bein des Benutzers ein hohes Rahmenteil überwinden um sich dann auf den Pedalen abstützend auf den Sattel zu setzen. Das ist für Menschen mit Behinderung oder ältere Menschen oft sehr schwierig.
- 2: Die bekannten Front Dreiräder mit starrer Vorderachse verleiten den Fahrer seinen Körper in der Kurvenfahrt entgegengesetzt zur Lenkrichtung zu neigen und somit den Schwerpunkt ungünstig für die Kippsicherheit des Fahrzeugs zu verlagern.
- 3: Durch den konstruktionsbedingten großen Abstand zwischen dem Sattel und den Vorderrädern bei handelsüblichen Front-Dreirädern wird das Kippverhalten in Kurvenfahrten negativ beeinflusst.
- 4: Die konstruktionsbedingte aufrechte Sitzposition von Benutzern der Frontdreiräder herkömmlicher Bauart bewirkt, dass sich der Schwerpunkt des Fahrers in großer Höhe vom Boden befindet und sich somit negativ auf das Kippverhalten des Fahrzeugs auswirkt.
- 1: For sitting on the saddle, one leg of the user has to overcome a high frame part in order to then sit on the pedals supporting on the saddle. This is often very difficult for people with disabilities or the elderly.
- 2: The known front three-wheelers with a rigid front axle tempt the driver to lean his body in cornering opposite to the steering direction and thus to shift the focus unfavorable for the tilting safety of the vehicle.
- 3: Due to the design-related large distance between the saddle and the front wheels in commercial front-wheel trikes, the tilting behavior is negatively influenced when cornering.
- 4: The design-related upright seating position of front tricycle users of conventional design causes the driver's center of gravity to be at a great height from the ground, thus adversely affecting the vehicle's tilting behavior.
Problemlösung:Troubleshooting:
Problem 1 wird mit dem im Schutzanspruch 1 beschriebenem Merkmal gelöst, das die Rahmenkonstruktion im Bereich zwischen Sitzschiene
Problem 2 wird mit dem im Schutzanspruch 4 beschriebenen Merkmal gelöst, das die Vorderachse als Pendelachse
Problem 3 wird mit dem im Schutzanspruch 7 beschriebenen Merkmal gelöst, dass die Treteinheit
Problem 4 wird mit dem im Schutzanspruch 8 beschriebenen Merkmal gelöst, dass durch die Ausgestaltung einer flach geneigten Sitzschiene
Ausführungsbeispiel:Embodiment:
Die Erfindung wird nachfolgend anhand der zugehörigen Zeichnungen erläutert.The invention will be explained below with reference to the accompanying drawings.
